' COMBINED SCRAPER AND HARROW.

SPECIFICATION forming part of Letters Patent No. 263,978, datedSeptember 5, 1882.

Application filed May 10, 1882. (Modem To all whom it may concern Be itknown that I, THOMAS MARTIN SMITH, of Batesville, in the county ofIndependence and State of Arkansas, have invented a new and usefulImprovement in Combined Scrapers and Harrows, of which the following isa full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan viewof my improvement. Fig. 2 is a sectional sideelevation of the same, taken through the line as m, Fig. 1. Fig.3 is afront elevation of the same, part being broken away.

The object of this invention is to produce a machine constructed in sucha manner as to scrape and cultivate a row of cotton or other plants atone passage along the said row.

The invention consists in a combined scraper and harrow, constructed aswill be hereinafter fully described.

A is the frame of the machine, which consists of three longitudinalbars, connected at their ends by two cross-bars. The ends of thecross-bars are bent downward to receive the bolts B, that fasten them tothe ends of the side bars.

0 are two runners or bearing-bars, which are designed to slide upon theground at the opposite sides of the ridge or row. The front and rearends of the runners C are curved upward into vertical positions, and areslotted vertically to receive the bolts B, that fasten them to the frameA, so that the said frame and its attachments can be raised and lowered,as the work to be done may require, by loosening the said bolts B.

D are the scrapers,which are secured to in.- clined bars E by bolts F.The bars E are slotted longitudinally to receive the clampingbolts F, sothat the scrapers D can be adjusted with their forward ends nearer to orfarther from each other, as the work to be done may require. The forwardends of the bars E meet, are welded together or are fitted to eachother, are passed through a slot in the standard G, and are secured toeyes formed upon the lower ends of the parts of the said standard by abolt, H. The upper part of the standard G rests against the forward sideof an upright, I, formed upon or attached to the forward end of thecenter bar of the frame A, and which is strengthened in position by abrace, J, formed upon or attached to its upper end. The lower end of thebrace J is secured by a bolt or rivet to the center bar of the frame A.

K is a bolt, which passes through the slot in the standard G and througha hole in the upright I, so that by loosening the said bolt the standardG, and with it the forward ends of the bars E and scrapers D, can heraised and lowered as the work to be done may require. The rear ends ofthe inclined slotted bars E are bent to the rearward, so as to beparallel with the side bars of the frame A, and are secured by bolts Lto the slotted end parts of the cross-bar M, so that by loosening thesaid boltsLthe rear ends of the bars E and scrapers D can be raised andlowered as may be required. The bar M is slotted longitudinally, crossesthe top of the frame A, is bent downward at the side bars of the saidframe, and is secured to the said side bars by bolts N. The lower endsof the slotted cross-bar M are secured to the runners G by rivets. Themiddle part of the cross-bar M is curved to the rearward, as shown inFig. 1, to bring it into proper position to receive the bolts 0, thatsecure to it the forward ends of the barrow or cultivator beams P, sothat the said forward ends can be adjusted farther apart or closertogether, as may be required. The rear ends of the beams P are securedby bolts Q to the end parts of the rear cross-bar of the frame A. 7

R are the harrow or cultivator teeth, the shanks of which pass up at thesides of the beams P, and are clamped to the said beams by hookbolts S,so that the said teeth can be adjusted to work deeper or shallower inthe ground, as may be required.

To the side bars of the frame A, at a little distance from their rearends, are bolted the forward ends of the handles T, the rear parts ofwhich are connected by a round, U, and which are supported at the properelevation by a standard, V, attached to the center of the round U and tothe rear part of the center bar of the frame A.

With this construction the machine can be readily adjusted to cause thescrapers D and the teeth R to work at any desired distance 2. Inacombined scraper and harrow, the
